I agree 100%. Free (wave, ride, race, move) boards do an excellent job of meeting the needs of almost all recreational riders. You can see my lineup below and the HiFly Move 105 is by far the most fun to sail if the wind is over 15-18 knots. Smooth, jibes great, jumps well and is fast.
On the other hand, what you use depends on where you live and sail, plus the typical conditions. Where I live, the winds are very gusty and variable, so the Formula and ISonic work great for maintaining a plane in the marginal winds. Below is my usage stats from 2010. I have every outing documented for the last 7 years with all the appropriated readings off my GPS.
